Déconnexions Wi-fi intempestives depuis quelques jours.
Bonsoir 
J'avais un problème de connexion Wi-fi sous Kubuntu 14.04 LTS 64 bits sur un PC portable de base Lenovo.
Ce souci ne venait pas du routeur puisqu'un autre PC sous Windows fonctionne toujours bien en Wi-fi.
Alors sagement, avant de poster ici, j'ai saisi les lignes de commandes conseillées dans À lire avant de poster !!!.
Et tout d'un coup, avant que je n'aie terminé, la Wi-fi s'est rétablie sur ma bécane. 
Bravo, mais comment expliquez-vous ça ?
Bonne soirée.

François, débutant sur Linux depuis Avril 2014. Divers OS Linux en multiboot.
Je pleurais car je n'avais pas de chaussures, puis je vis un homme qui n'avait pas de pieds.

Re : Déconnexions Wi-fi intempestives depuis quelques jours.
Bonsoir
Ça a recommencé : déconnexions Wi-fi intempestives (j'ai branché en filaire pour pouvoir poster ici.).
Alors je vous expose le résultat de la liste de commandes conseillées ici https://forum.ubuntu-fr.org/viewtopic.php?id=141183 :

Re : Déconnexions Wi-fi intempestives depuis quelques jours.
Apparement le wifi est bien détecté tu es sur le bon canal avec un bon rapport.
S'il y a des deconnexions bizarres ce peut être dû à une instabilité de ton FAI au niveau de la box, cela m'est arrivé et pendant 4 jours j'ai dû changer de canal sur la Freebox mais ç'est rare; je ne sais quoi ajouter. Si Michel passe par ici il pourra te conseiller.
